In this way, on the basis of the adhesion between the side face of the connecting rib 6 and the inner wall face of the dust cup inner tube 2, the connecting rib 6 is provided between the stopper 5 and the bottom end of the dust cup inner tube 2, and the stopper 5 can be supported, so that the connection stability of the stopper 5 and the inner wall face of the dust cup inner tube 2 can be further improved.

The structure of the dust blocking part 3, specifically, the structure is a split structure, and includes a connection ring 31 and a plurality of dust blocking sheets continuously arranged along the radial direction of the connection ring 31, the fixed end of the dust blocking sheet is fixedly connected with the connection ring 31, the suspended end of the dust blocking sheet is suspended, and the connection ring 31 is detachably sleeved with the top end of the dust cup inner tube 2. Thus, through the dust blocking part 3 which is arranged in a split way, when the dust collection cup body is in an assembly state (namely, the fluid pipeline assembly is inserted into the dust cup inner tube 2), under the action of the fluid pipeline assembly, the suspended end of the dust blocking sheet is bent from the top end of the dust cup inner tube 2 to the bottom end of the dust cup inner tube 2, and the dust blocking part 3 is in an open position, so that the circulation of fluid in the fluid pipeline assembly is realized; when the dirt cup body is in the dismantlement state (dirt cup inner tube 2 and fluid pipeline subassembly separation promptly), a plurality of fender dirt pieces constitute complete continuous face, and fender dirt portion 3 is in the closed position, shelters from dirt cup inner tube 2 to can avoid leaking the condition to the dirt cup outside through dirt cup inner tube 2 in the dirt cup body clearance process.

In order to facilitate the insertion of the fluid conduit assembly, the dust-blocking portion 3 is tapered, and the tip of the taper is directed toward the bottom end of the inner tube 2 of the dirt cup. Thus, when the fluid line assembly is inserted from the top end of the inner tube 2 of the dirt cup, the dust guard 3 can be separated smoothly, switching from the closed position to the open position.

In order to facilitate the bending of the dust-blocking sheet, the dust-blocking sheet comprises a bending section 32 and a dust-blocking section 33, the dust-blocking section 33 is fixedly connected with the connecting pipe through the bending section 32, wherein the bending section 32 is rectangular, and the dust-blocking section 33 is triangular, that is, the dust-blocking sheet is arrow-shaped. In this way, the dust blocking section 33 mainly plays a role of blocking dust, the bending sections 32 are narrow, and a gap (i.e., a hollow area) is formed between every two adjacent bending sections 32, so that bending is facilitated.

In order to facilitate the bending of the dust-blocking sheet, the position of the bending section 32 may correspond to the gap position of the stopper 5, so that when the bending section 32 is bent, the gap can provide a larger bending space for the bending section 32, thereby facilitating the bending of the dust-blocking sheet.
